For Igneous Rocks: Since igneous rocks are made from magma, we want to melt the chocolate first. Adult supervision is recommended for this step!! In the microwave, heat up a cup of water until almost boiling. Wrap a square of chocolate in a piece of aluminum foil. Place the foil packet...
Hot, liquid rock, called magma (岩浆), flowed up slowly from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today. That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of a plate under ...

These are called intrusive igneous rocks because they are formed “inside” the earth. If magma makes it to the surface, or close to the surface, it cools ___ and the rocks formed may look ___ or contain ___. These are called extrusive igneous rocks. List two common igneous rocks: 1...
rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks. Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the ...
The zircons of the tuffs have εHf(t) values ranging from+2.6 to+8.6, with two-age Hf model age being 590~925Ma, which suggests that the magma for these volcanic rocks was derived from the newly accreted Early Paleozoic-Neoproterozoic juvenile crustal materials. The tuffs of Manketou'ebo ...
These geochemical characteristics show that the Meisu rhyolite is the product of mixing/contamination by a specific proportion of alkali-rich, Nb-Ta enriched, mantle-derived basaltic magma and crust-derived magma. The authors hold that the Meisu rhyolite was formed in an intraplate extension environ...
